How it holds itself in place

Here is the loop that follows from that. Follow it round once. Notice that nothing in it requires you to be doing grief wrongly. It runs perfectly well on ordinary people being uncomfortable.

The lossNo witness, noritualOthers say nothingYou stop mentioningitCarried alone, selfblame
Intrusive images, nightmares or avoidance that keeps spreading are not this loop. Route to a clinician. The diagram shows a loop running through: The loss, then No witness, no ritual, then Others say nothing, then You stop mentioning it, then Carried alone, self blame.
